This patent application claims the benefit of U.S. patent application Ser. No. 15/800,469, filed on Nov. 1, 2017, and U.S. patent application Ser. No. 15/821,538, filed on Nov. 22, 2017, both of which are incorporated herein by reference in their entirety.
The present disclosure generally relates to devices for deterring drug abuse and methods thereof. More particularly, the disclosure relates to devices for deterring drug abuse by using physical deterrents and/or deterrent substances, including a locking mechanism that dispenses a deterrent substance when the drug is improperly accessed. The present disclosure also relates to methods of accessing a drug from such devices.
The opioid crisis has greatly increased the risk of medication diversion, i.e., when a legal controlled substance is used illegally. The drug theft occurs frequently in outpatient facilities, but can happen anywhere. The theft can come from a number of sources including the patient, friends and family of the patient, and even health care workers struggling with addition. Stealing medication from an IV line or a syringe and replacing it with another substance to prevent detection can lead to dangerous bloodstream infections.
It is against the above background that the present invention provides certain advantages and advancements over the prior art. Although this invention as disclosed herein is not limited to specific advantages or functionality, the invention disclosed herein provides devices and methods for deterring drug abuse.
In one aspect, the disclosure comprises a device for deterring drug abuse comprising a housing configured to contain a drug that can be accessed through an access port of the housing; a physical deterrent configured to move from an unsecured position, wherein the access port of the housing is normally accessible, to a secure position, wherein the access port of the housing is normally inaccessible; a locking mechanism coupled with the physical deterrent, the locking mechanism including a locked mode, wherein the physical deterrent is not normally able to move from the secure position to the unsecured position; the locking mechanism further coupled with a deterrent container that has a deterrent substance therein; and the device is configured such that attempts to access the drug through the access port: a) when the physical deterrent is in the secure position, and b) when the locking mechanism is in the locked mode, activate the release of the deterrent substance to the drug.
In some embodiments, the drug may be accessed by moving the physical deterrent relative to the housing. To that end, the physical deterrent may be oriented relative to the housing in such a way as to prevent and/or significantly hinder access to the access port when in the locked mode, and the physical deterrent may be oriented relative to the housing in such a way to allow access to the access port when in the unlocked mode.
In some embodiments, the device further comprises a rod that connects the housing and the physical deterrent; the rod being normally movable in the unlocked mode, to allow for the physical deterrent to transition from the secure position to the unsecure position; the rod further being normally immobile in the locked mode, to prevent the physical deterrent from transition from the secure position to the unsecure position; the movement of the rod changing the orientation of the housing relative to the physical deterrent.
In some embodiments, the housing is rotatable relative to the physical deterrent in the unlocked mode, and the housing is not rotatable relative to the physical deterrent in the locked mode. In some embodiments, the housing is an IV fluid bag, a vial, a syringe, a canister, or a bottle.
In some embodiments, the deterrent substance is a drug antagonist, a chemical irritant, a gelling agent, a colorant, an emetic, and/or an encapsulating agent. In some embodiments, the deterrent substance has a foul odor.
In another aspect, the disclosure comprises a device for deterring drug abuse comprising a housing configured to contain a drug that can be accessed through an access port of the housing; a locking mechanism coupled with the housing, the locking mechanism has a locked mode wherein the access port is closed, and an unlocked mode wherein the access port is open; the locking mechanism further coupled with a deterrent container configured with a deterrent substance therein, wherein attempting to access the drug when the locking mechanism is in the locked mode activates the release of the deterrent substance to the drug.
In some embodiments, the device further comprises a physical deterrent coupled with the locking mechanism, wherein the housing is not normally movable relative to the physical deterrent in the locked mode. In some embodiments, the locking mechanism may have an unlocked mode where the physical deterrent is normally able to move from the secured position to the unsecured position. In some embodiments, the physical deterrent may be a lid of a container, a cap or a box. The deterrent device may be internal, external, and/or built-in to the housing.
In some embodiments, a plug may keep the deterrent substance in the deterrent container. Among other ways, pressurized gas from walls of the housing may support the plug. Additionally, or alternatively, a spring may support the plug. Alternatively, or additionally, the housing may contain wires that detect attempts to access the drug.
In some embodiments, the locking mechanism includes a padlock, combination lock, and/or biometric scanner. In some embodiments, the locking mechanism is coupled to a timer and the locking mechanism locks after a predefined or predetermined time. In some embodiments, the locking mechanism is coupled to a dosage counter and the locking mechanism locks after a predefined or predetermined dosage has been released from the housing.
Some embodiments may include a touchscreen interface. The touchscreen may provide reminders regarding a drug dosing schedule. The touchscreen interface may be configured to receive a passcode, and if a correct passcode is entered, the drug may be dispensed, for example, through a chute. In some embodiments, a carousel dispenses the drug through the chute. In some embodiments, a sensor may detect tampering with the chute, and open a valve that reduces the pressure in the walls of the housing, the plug will no longer block the deterrent container, and the deterrent substance is released. In some embodiments, the valve may be opened after a specified time interval, such as one-month, three-months, six-months, or after an expiration date of the drug. Additionally, or alternatively, a signal may be sent, for example from a medical provider through Wi-Fi, to open the valve.
In some embodiments, the housing may include an IV fluid bag, a vial, a bottle, a canister, and/or a syringe. In some embodiments, cutting a wall of the housing may release the deterrent substance. To that end, the housing may have hollow walls filled with pressurized gas (e.g., pressurized air and/or compressed nitrogen). When the walls are cut (e.g., by someone trying to improperly access the drug by cutting through the wall), the pressure drop activates the release of the deterrent substance. Additionally, or alternatively, the housing wall may be covered in a matrix of electrically conductive material, e.g., wire. When the electrically conductive material is cut (e.g., by someone trying to improperly access the drug by cutting through the wall), the release of the deterrent substance is activated.
In another aspect, the disclosure comprises a method of accessing a drug provided inside a housing having a physical deterrent and a chemical deterrent comprising providing a housing configured to contain a drug, the housing having an access port through which the drug can be accessed; a movable physical deterrent that blocks the access port of the housing when the physical deterrent is in a secure position; a locking mechanism that prevents and/or significantly hinders the physical deterrent from moving from the secure position to an unsecured position, wherein the physical deterrent no longer blocks the access port in the unsecured position; and a deterrent container configured to hold a deterrent substance therein that is released when the drug is accessed while the physical deterrent is in the secure position and the locking mechanism is in the locked mode; unlocking the locking mechanism; moving the physical deterrent into the unsecure position; and accessing the drug.
Those skilled in the art should more fully appreciate advantages of various embodiments of the invention from the following “Description of Illustrative Embodiments,” discussed with reference to the drawings summarized immediately below.
Before the disclosed devices and methods are described in detail, it is to be understood that the aspects described herein are not limited to specific embodiments or configurations and, as such, can vary. It is also to be understood that the terminology used herein is for the purpose of describing particular aspects only and, unless specifically defined herein, is not intended to be limiting.
It is also to be understood that, unless clearly indicated otherwise by the context, embodiments disclosed for one aspect or embodiment of the disclosure can be used in other aspects or embodiments as well, and/or in combination with embodiments disclosed in the same or other aspects of the disclosure. Thus, the disclosure is intended to include such combinations, even where such combinations have not been explicitly delineated.
Throughout the specification, unless the context requires otherwise, the word “comprise” and “include” and variations (e.g., “comprises,” “comprising,” “includes,” “including”) will be understood to imply the inclusion of a stated component, feature, element, or step or group of components, features, elements or steps but not the exclusion of any other integer or step or group of integers or steps.
It is noted that terms like “preferably,” “commonly,” and “typically” are not utilized herein to limit the scope of the claimed invention or to imply that certain features are critical, essential, or even important to the structure or function of the claimed invention. Rather, these terms are merely intended to highlight alternative or additional features that can or cannot be utilized in a particular embodiment of the present invention.
As used in the specification and the appended claims, the singular forms “a,” “an” and “the” include plural referents unless the context clearly dictates otherwise.
Values can be expressed herein as approximations by use of the antecedent “about,” and it is understood that the particular value forms an aspect. Similarly, ranges can be expressed herein as from “about” one particular value, and/or to “about” another particular value. When such range is expressed, another aspect includes from the one particular value and/or to the other particular value. It will be further understood that the endpoints of each of the ranges are significant both in relation to the other endpoint, and independently of the other endpoint.
As used herein, the term “drug” includes pharmaceutical medications and pharmaceutical drug products. The pharmaceutical medication or drug can be in liquid, pill, tablet, capsule, gel cap, powder or any other form appropriate for any of the devices, containers and methods disclosed herein.
As used herein, the term “deterrent substance” or “chemical deterrent” may be one or more of a drug antagonist (e.g., naloxone, naltrexone, methylnaltrexone, nalmefene, etc.), a colorant (e.g., bright colorant), an emetic (e.g., ipecac syrup), a foul odor (e.g., pepsin, butanethiol, etc.), a foul tasting agent (e.g., Bitrex® or Denatonium Benzoate), a gelling agent, an encapsulating agent (e.g., glue), a flushing agent (e.g., niacin), and/or an irritant (e.g., capsaicin), each of which are identified as non-limiting examples. Other useful opioid receptor antagonists are known (see e.g., Kreek et al., U.S. Pat. No. 4,987,136).
In illustrative embodiments a device provides secure access to a drug and deters unauthorized access of the drug. The device includes a locking mechanism coupled to a physical barrier that prevents and/or mitigates access to the drug by unauthorized users, unauthorized dosages, and/or at unauthorized times. If the housing is improperly breached, a chemical deterrent is released. The chemical deterrent mixes with the drug, making the drug unsuitable for use.
Prior art drug delivery and administration methods generally require multiple steps and multiple intermediate parties to deliver the drug 4 from manufacture to patient 8. For example, a pharmacist at the hospital may need to compound the drug 4, a health care worker may transfer the drug 4, and a nurse 10 may deliver the drug 4. Other situations where this may arise include, for example, in a hospital, nursing home, palliative care, or substance abuse treatment center settings. It is also possible that a patient 8 may seek to abuse illicit or prescription drugs 4 and inject them into their own intravenous (IV) set 12. It is also possible to steal and abuse prescription IV drug sets 12. Thus, the prior art methods have high potential for drug 4 diversion and/or abuse. Furthermore, in some cases, the drug 4 may be left unattended/unmonitored for periods of time (e.g., in an IV bag 14 connected to a sleeping patient 8). Thus, the patient 8, health care workers, patient's friends and family as well as others have the ability to illegally remove/take some, or the entirety, of the legally prescribed drug 4. Illustrative embodiments deter the abuse of drugs 4.
Illustrative embodiments of the invention may be integrated into the IV set 12 by providing a physical deterrent and a chemical deterrent. Thus deterring the use of the IV set 12 for abuse of illicit or prescription drugs 4. Illustrative embodiments may be useful, for example, when the IV set 12 is used to administer prescription pain killers 4. Drugs 4 such as morphine sulphate, hydromorphone, fentanyl, and methadone are particularly susceptible to abuse. When contained in a prescription IV set 12, the set deters the removal, contamination, insertion, over-administration, or abuse of the drug 4. Illustrative embodiments also deter the insertion of drugs 4 of abuse into an IV set 12.
Although the terms “spike” and “port” are used to distinguish different access points of the drug 4, both of these terms are considered to be “access ports” of the housing, i.e., the drug 4 may be accessed through these fluid passageways. Furthermore, although illustrative embodiments are described as having a “spike” and “port” it should be understood that these are merely exemplary and that illustrative embodiments are not limited to having a spike and/or a port. For example, although some embodiments are described as having the spike 3, other embodiments may not have the spike 3. Instead, for example, intermediary tubing 18 may connect the access port (shown as spike 3) to another spike outside of the device 2 that then connects to the IV bag 14.
In some embodiments, walls 5 of the device 2 are formed from an impervious material, such as polycarbonate, polypropylene, polyethylene, terephthalate, high density polyethylene, polyvinyl chloride, polystyrene, polylactide, and/or glass (e.g., chemically strengthened glass). The walls 5 (and the device 2) may be integrally formed with the cylinder 24, or the cylinder 24 may be positioned within the walls of an independent device 2. The walls 5 are of a sufficient thickness and rigidity to prevent and/or significantly mitigate squeezing of the cylinder 24 (e.g., as by a human grip trying to deform and/or open the cylinder 42). The walls 5 also prevent and/or significantly mitigate unauthorized penetration by needles.
On both ends of the cylinder 24 are physical deterrents. The physical deterrents may be, for example, caps 28 that are attached to the wall 5 by a secure hinge 7. In illustrative embodiments, the caps 28 may be formed from polycarbonate, polypropylene, polyethylene terephthalate, high density polyethylene, polyvinyl chloride, polystyrene, polylactide, glass (e.g., chemically strengthened glass), and/or another clear material that is sufficiently thick and rigid to prevent and/or significantly hinder needle penetration and/or easy breaking of the caps 28.
When the physical deterrent is positioned in such a way as to significantly hinder and/or prevent physical access to the drug 4, the physical deterrent 20 is in a secure position.
The caps 28 are lockable either by multiple locking mechanisms 32 on the top and bottom, or by a single locking mechanism 32 that locks both the top and bottom. The lock 32 may be an external lock (e.g., a padlock) or integrated into the device 2 (e.g., biometric scanner). The lock 32 may be opened by a key, keypad, combination lock, or other suitable mechanism.
The hinge 7 and/or lock 32 attachment may be anchored 36 to a compartment 34 (also referred to as a “deterrent container 34”) that houses a deterrent substance such as, for example, a drug antagonist, such as naloxone, a gelling agent, and/or other deterrent substance such as capsicum. The anchor 36 is attached to the cylinder 24 wall by glue, lamination, and/or some other semi-permanent or permanent means. If one or more of the caps 28 is forced open, the anchor 36 breaks away from the cylinder 24 and tears open the deterrent container 34 and releases the deterrent substance into the main compartment of the cylinder 24 where it contacts the drug 4. Accordingly, the drug 4 in the cylinder 24 is rendered unsuitable for use and abuse of the drug 4 is deterred. Illustrative embodiments do not necessarily require the anchor 36 and/or the compartment 34.
When the physical deterrent 20 is in the secured position (e.g., cap 6 is closed), and the locking mechanism is in the locked mode (e.g., padlock 32 is locked and keeps the caps 6 in their position), as shown in the figure, the drug 4 is normally inaccessible. This means that a user is not able to open the container and access the drug 4. The term “normally” is used to refer to situations where a user may try to open the device 2 with his or her hands, and includes the forces that the device may encounter in its ordinary use. “Normally” distinguishes other situations where power tools and/or other tools and methods may be used to break apart the physical deterrent and/or the locking mechanism 32. Accordingly, if the physical deterrent is opened when the device 2 is in the closed mode and the locking mechanism is locked (e.g., by an unauthorized user), the deterrent substance is released. Conversely, if the physical deterrent 20 is opened when the device 2 is in the opened mode and the locking mechanism is unlocked (e.g., by an authorized user), the deterrent substance is not released.
The physical deterrent 20 may have a small slit or hole 38 to allow IV tubing 16, 18 to remain connected to the device 2 while the physical deterrent 20 is in the secured position. Even in such a configuration, the access port of the housing 1 is considered to be “normally inaccessible.” Although illustrative embodiments are shown as blocking access to the outside of the access port, it should be understood that some embodiments may have the physical deterrent 20 internal to the housing 1 and block the access port internally.
The cylinder 24 is securely integrated inside a physical deterrent 20 (e.g., rectangular box 40, shown as a partial rectangle), which may be formed from an impervious material, such as polycarbonate, polypropylene, polyethylene terephthalate, high density polyethylene, polyvinyl chloride, polystyrene, polylactide, glass (e.g., chemically strengthened glass). The walls 5 of the physical deterrent 20 are of a sufficient thickness and rigidity to prevent and/or significantly hinder squeezing of the cylinder 24. The walls 5 also prevent and/or mitigate unauthorized penetration by needles. This is a mechanism to prevent and/or significantly hinder and/or deter abuse of the drug 4 contained within.
In some embodiments, the housing 1 is connected with the physical deterrent (e.g., barrier 40) at a pivot point 46 that allows the housing 1 to rotate partially or entirely within the barrier 40. For example, the middle of the housing 1 is connected to the middle of the barrier 40 by the pivot point 46 that allows the housing 1 to rotate partially within the barrier 40. There is an opening 7 on opposite ends of the top and bottom of the barrier 40.
Illustrative embodiments may contain naltrexone as, or part of, the deterrent substance. Naltrexone (e.g., naltrexone hydrochloride) is an opioid antagonist. Naltrexone markedly attenuates or completely blocks, reversibly, the subjective effects of intravenously administered opioids. Illustrative embodiments may administer a drug antagonist (such as, for example, Naltrexone) that is not associated with the development of tolerance or dependence. Clinical studies indicate that 50 mg of naltrexone hydrochloride may block the pharmacologic effects of 25 mg of intravenously administered heroin for periods as long as 24 hours. Other data suggest that doubling the dose of naltrexone hydrochloride provides blockade for 48 hours, and tripling the dose of naltrexone hydrochloride provides blockade for about 72 hours. There is limited clinical experience with naltrexone over dosage in humans. In one study, subjects who received 800 mg daily naltrexone hydrochloride for up to one week showed no evidence of toxicity.
In the mouse, rat and guinea pig, the oral LD50s were 1,100 to 1,550 mg/kg; 1,450 mg/kg; and 1,490 mg/kg; respectively. High doses of naltrexone hydrochloride (generally >1,000 mg/kg) produced salivation, depression/reduced activity, tremors, and convulsions. Mortalities in animals due to high-dose naltrexone administration usually were due to tonic-clonic convulsions and/or respiratory failure. Illustrative embodiments of the device 2 may contain between about 10 mg and about 1200 mg of Naltrexone as the chemical deterrent. Some other embodiments may contain a fixed dose of antagonist per unit dose of drug 4 (e.g., opioid). Other embodiments may contain a fixed dose of antagonist per unit dose of drug 4 (e.g., opioid). As an example, between 2.5 mg and 30 mg of antagonist may be used per drug dose. Furthermore, illustrative embodiments contain a dosage of chemical deterrent that preferably does not cause over dosage in humans.
The housing 1 is enclosed in the physical deterrent 20 (e.g., larger cylinder 20) formed from an impervious material such as polycarbonate, polypropylene, polyethylene terephthalate, high density polyethylene, polyvinyl chloride, polystyrene, polylactide, and/or glass (e.g., chemically strengthened glass). The walls are of a sufficient thickness and rigidity to prevent and/or significantly hinder squeezing of the cylinder 24. The walls also prevent and/or significantly hinder unauthorized penetration by needles. This is a mechanism to prevent and/or significantly hinder and or deter abuse of the device or drug contained within. The impervious cylinder has caps 28 on both ends. The caps have a hole 38 toward the side of the top or bottom. A central rod 42 runs from the middle of the upper cap 28 to the middle of the lower cap 28. The inner cylinder 24 can rotate on the rod 42. When the reconstitution cylinder 24 rotates within the impervious cylinder 20 in one position (i.e., the unsecured position) the access ports 3 and 22 line up with the holes 38 and are accessible (as shown in
In another position (i.e., the secured position—not shown) the access ports 3 and 22 are shielded and are inaccessible. A locking mechanism 32 can lock the position of the inner cylinder 24 either in the unsecure or secure position. If the holes 38 on the impervious cylinder 5 are on diagonal ends, it would allow for operations such as filling the reconstitution cylinder 24 through spike 3 while preventing and/or significantly hindering access to the access port 22. Then the access port 22 could be rotated to be accessible while preventing and/or significantly hindering access to the top spike 3. Additionally, or alternatively, if the inner cylinder 24 is manufactured with a constituted drug 4 inside, there may be no need to have a hole 38 for filling the reconstitution cylinder 24. The rod 42 may be anchored to a container 10 that houses one or more deterrent substances such as, for example, an antagonist, such as naloxone, a gelling agent, and/or other deterrent substance, such as capsicum. If the cylinder 24 is forced to open in the secured position, then the container 34 ruptures and releases the deterrent substance into the cylinder 24. Thus, the contents are rendered unfit for use, and thereby deter abuse.
Preferably, the device 2 may be provided in a sterile packaging and may have a premeasured amount of the drug 4 in the cylinder 24. Moreover, the device may be provided in tamper-evident packaging.
Furthermore, the cylinder 24 may be fluidly connected with the IV fluid bag 14. This connection facilitates the reconstitution of the drug 4. Alternatively, or additionally, the cylinder 24 may come prepackaged with a constituted drug 4. In this case the cylinder 24 does not need to be configured to connect to an IV bag 14. The tubing 18 additionally may be connected to the patient 8. To facilitate delivery of the drug 4 to the patient 8, the cylinder 24 may be fluidly connected with the tubing 18 connected to the patient 8.
The shell 44 can be a hollow sphere. The sphere 44 may be made in two parts that are connected by a hinge 7. A locking mechanism 32, such as a padlock, may be inserted through two holes 48 on the sphere 44 and then locked. The locking mechanism 32 can also be integrated into the sphere 44 (e.g., biometric scanner). In some embodiments, the sphere 44 also has at least two holes 38 to allow IV tubing to be connected while in the secured position. One hole 38 is for the IV line 16 to enter from the IV bag 14 or reconstitution cylinder. The other hole 38 is for the tubing 18 to exit to the patient 8.
Illustrative embodiments include a plunger 52 that pushes the drug 4 through the needle 54. A firing pin 56 holds the plunger 52 in place. The firing pin 56 is secured to an outer cylinder 58, and the outer cylinder 58 is secured to the inner cylinder 24. The outer cylinder 58 can also be distally anchored to the rod 42 and or deterrent container 34. Removing the firing pin 56 allows the spring 57 to push the plunger 52 and inject the medicine in the cylinder 24 into the to patient through the needle 54.
The syringe is held inside a physical deterrent 20, such as rectangular box 40. The rectangular box 40 may me formed from a rigid material, such as a hard plastic. Additionally, the box 40 may be formed from clear plastic such as polycarbonate, polypropylene, polyethylene terephthalate, high density polyethylene, polyvinyl chloride, polystyrene, and/or polylactide. One side of the box 40 is open. The syringe 50 is secured in the box 40 on one side by a pivot 46. The pivot 46 allows the syringe 50 to rotate out of the box 40 so that the needle 54 may insert into a patient 8 for the purpose of administering a medicine. On the other side, the syringe 50 is held by a rod 42 that is secured to the box 40 by a lock 32.
The rod 42 is anchored to the deterrent container 34 having a deterrent substance. Although the deterrent container 34 is shown as taking up only part of the bottom of the cylinder 24, it should be understood that the container 34 can be modified to fill more or less of the volume of the cylinder 24 and to adjust the amount of medicine that is left after use. If the syringe 50 is forced into the unsecured position (not shown), the deterrent container 34 ruptures and releases the abuse deterrent substance into the cylinder 24 to render the drug 4 unfit for abuse. The deterrent container 34 can be, for example, ripped open when it is pulled away from the rod 42.
As an example, if the cylinder 24 was filled with an opioid 4, the deterrent container 34 may be filled with an opioid antagonist, such as naloxone, naltrexone, and/or a gelling agent. In illustrative embodiments, the rod 42 may have an additional arm 62 that extends around the needle 54. If the syringe is forced open, the arm 62 bends the needle 54 so it cannot be used
Illustrative embodiments include a sponge 64 that is coated or otherwise impregnated with the chemical deterrent. The sponge 64 may be opposite the needle 54. If the firing pin 56 is activated in the secured position (as shown in
Illustrative embodiments do not require a spring 57, firing pin 56 and/or the outer cylinder 58 to cover more than half the length of the inner cylinder 24. The outer cylinder 58 may slide freely on the inner cylinder 24. The syringe 50 may be manually injectable. When the syringe 50 is unlocked, it may be injected by pressing the needle 54 into the patient 8 and pushing the syringe 50 down to collapse the outer cylinder 58 and inner cylinder 24 to administer the medicine.
The inner bottle 24 is housed inside the physical deterrent 20. In illustrative embodiments, the physical deterrent may be an outer cylinder 68 formed from a hard material such as polycarbonate. The inner bottle 24 is attached to the outer cylinder 68 by a pivot 46 which allows the inner bottle 24 to partially rotate relative to the outer cylinder 68. The inner bottle 24 has a top that may cut at an angle to be able to seal tightly against an angled portion of the outer cylinder 68. In
The bottle 66 is not allowed to freely pivot by a rod 42. The rod 42 can be attached to either side or the bottom of the bottle 66. The rod 42 can be locked to the cylinder 68 by a lock 32, such as a padlock. When locked, the pharmaceuticals 4 are inaccessible. The rod 42 is anchored to a container 34 that houses one or a combination of deterrent substances such as, for example, a drug antagonist (e.g., naloxone or naltrexone), a bright colorant, an emetic (e.g., ipecac syrup), a foul odor (e.g., pepsin or butanethiol), a gelling agent, an encapsulating agent (e.g., glue), a flushing agent (e.g., niacin), and/or an irritant (e.g., capsaicin). If illustrative embodiments of the invention are forced into the open position (e.g., when in the locked mode), the container 34 ruptures and spills or sprays the abuse deterrent substance on the drug 4. The substance in the container 34 can be brightly colored to clearly indicate when the inner pharmaceutical 4 is sprayed. Alternatively, the substance may have no color.
Illustrative embodiments incorporate a physical abuse deterrent in the hard outer cylinder 68 and inner bottle 24. Illustrative embodiments of the invention also incorporate a chemical abuse deterrent in the form of the deterrent substance held within the container 34. The device can have a spring 70 that automatically closes the device after use.
In some embodiments, the walls 5 of the housing 1 may be hollow and filled with pressurized gas (e.g., pressurize air, and/or compressed nitrogen). The drug 4 can properly be accessed through an access port, such as opening 29. If someone improperly tries to access the drug 4 by cutting through the walls 5, or the lid 70, the pressure inside the wall 5 is changed. The change in pressure activates the release of the deterrent substance. Like many containers that hold drugs 4, the housing 1 has a physical deterrent, such as a lid 70.
In some embodiments, the wall 5 and/or lid 70 contains a deterrent trigger, such as an electrically conductive matrix (e.g., a matrix of wires 80). If the deterrent trigger is activated (e.g., wires 80 are broken and/or cut), this triggers the release of the plug 74 from the deterrent container 34 (e.g., by a solenoid that releases the plug 74 from the container 34), and the deterrent substance is positioned (e.g., sprayed) onto the drug 4. Thus, illustrative embodiments release chemical deterrent when the user cuts and/or breaks through the housing 1 and/or the physical deterrent.
The bottle has a security lock 32. The lock 32 in the figure is a rotating combination lock 32. The lock 32 actuates a bent rod 42 in a channel 72. When the lock 32 is in the unlocked mode, the rod 42 moves freely in the channel 72, allowing the lid 70 to open. When the lock 32 is in the locked mode, the rod 42 is trapped by the channel 72, and the lid 70 does not normally open. Forcing the lid 70 open in the locked mode causes the rod 42 to pull on the channel 72, which in turn pulls on the pin 56. In some embodiments, pulling on the pin 56 depressurizes the housing wall 5. Additionally, or alternatively, pulling on the pin 56 may release a plug 74 (e.g., in some embodiments the pin 56 in its resting state may hold the plug 74 in place—or may be attached to the plug 74).
The deterrent container 34 houses one or more deterrent substances such as, for example, a drug antagonist (e.g., naloxone, naltrexone, methylnaltrexone, and nalmefene), a bright colorant, a black colorant (e.g., that makes the drug 4 less visually appealing as well as indicating that the antagonist has deployed), an emetic (e.g., ipecac syrup), a foul odor (e.g., pepsin and/or butanethiol), a gelling agent, an encapsulating agent (e.g., glue), a flushing agent (e.g., niacin), and/or an irritant (e.g., capsaicin). Other useful opioid receptor antagonists are known (see, e.g., Kreek et al., U.S. Pat. No. 4,987,136).
The container 34 is normally pressurized such that the plug 74 keeps the deterrent substance in the container. When the plug 74 is removed from the container 34, the deterrent substance is positioned (e.g., sprayed) onto the drug 4. In some embodiments, the substance in the container 34 may be colored (e.g., brightly and/or with black colorant) to clearly indicate that the drug 4 has deterrent. A spring may automatically close and lock the device after use.
As with the embodiment shown in
The deterrent compartment 34 is pressurized, e.g., by containing an opioid antagonist, naltrexone, pepsin for essence, and/or a black colorant in a compressed aerosol foam formulation. In the absence of the plug 74, the pressurized contents in the deterrent compartment 34 are otherwise released/sprayed into the inside of the container and onto the drug 4 through a nozzle 82. To that end, the pressure inside the deterrent compartment 34 may be higher than the pressure inside of the drug 4 container and/or in the pressurized walls 5 of the container. In order for the plug 74 to prevent the accidental discharge of the contents within the deterrent compartment 34, the plug 74 provides sufficient counter pressure on the deterrent compartment 34 (e.g., on the nozzle 82). To that end, the back 84 of the plug 74 may be pressurized by the walls 5 and/or other parts of the housing 1. Under normal circumstances (e.g., when the housing 1 has not been cut open, and the pressure within the wall 5 is maintained) there is sufficient counter pressure provided by the plug 74 such that the deterrent substance is prevented from escaping the deterrent compartment 34.
In illustrative embodiments, if the housing 1 is improperly breached (e.g., cut open) then the pressure inside the walls 5 drops, and the plug no longer provides sufficient counter pressure to block release of the contents within the deterrent compartment 34. Thus, when the drugs 4 are improperly accessed, the plug 74 stops blocking the release of the contents within the deterrent compartment 34, and the contents are released/sprayed onto the drug 4. Additionally, or alternatively, a spring 86 may provide the counter pressure on the plug 74. In some embodiments, the pin 56 may, for example, remove the counter pressure provided by the spring 86 (e.g., by pulling the spring 86 away from the plug 74). The above described illustrative embodiments are merely exemplary, and not intended to limit various embodiments of the invention. A person of skill in the art can think of numerous other ways through which the release of the deterrent substance within the deterrent container 34 may be activated (e.g., electronically opening/closing nozzle 82 instead of the plug 84).
A person of skill in the art will be able to modify the device (e.g., shape and or material of the plug 74, shape and or material of the deterrent container 34, stiffness of spring 86, etc.) to prevent the accidental release of the deterrent substance in the compartment 34 during the normal use of the bottle. Thus, various embodiments may be configured to account for different circumstances that may be encountered normally in use (e.g., if a part of the bottle is accidentally crushed—some embodiments may account for this change in pressure and are configured not to release the deterrent 34 absent a certain threshold reduction in pressure of the walls 5).
The housing 1 may be any container, e.g., a pharmaceutical bottle formed from pharmaceutically acceptable material. The pharmaceutical bottle 1 can be formed from HDPE (high-density polyethylene), polypropylene, polyethylene terephthalate, high density polyethylene, polyvinyl chloride, polystyrene, polylactide, stainless steel, aluminum, and/or glass, and/or may be clear, tinted, or opaque. As described previously, the bottle may hold the drug 4 therein.
In some embodiments, the walls 5 of the housing 1 may be hollow and filled with pressurized air. In alternative embodiments, the walls may be filled with compressed nitrogen. Compressed nitrogen does not have water vapor in it and may keep the pressure within the walls 5 more steady than pressurized air. It should be understood that a variety of different compressed gases may be used, and that discussion of “air” is merely intended to facilitate discussion of illustrative embodiments, and not to limit them thereby.
The air pressure in the walls 5 pushes against a piston 109. At least a portion of the piston 109 is configured to move from the area of the pressurized bottle walls 5 (e.g., double layer walls) to the unpressurized environment inside the bottle (e.g., where the drugs 4 are). The piston 109 may be sealed with gaskets 112 to prevent pressure from escaping the bottle walls 5 while the piston 109 moves. In the embodiment shown, the tip 114 of the piston 109 presses into the abuse deterrent container 34 and seals it. When the tip 114 backs out of the abuse deterrent container 34, the pressure from the spring 86 pushes the plate 93 in the container 34, and causes the abuse deterrent substance, which is in the container 34, to spray out of the container 34 and down onto the medicine 4.
The tip 114 of the piston 109 may have a channel 95 through which deterrent substance may be dispensed. When the piston 109 partially backs out of the container 34, the channel 95 directs the abuse deterrent substance onto the drug 4. Thus, the channel 95 acts as a passageway that directs the deterrent substance towards the drug 4. In this manner, the pressure within the walls 5 keeps the abuse deterrent substance contained within the deterrent container 34.
If the drug 4 is improperly accessed (e.g., by cutting through the walls 5), the pressure inside the wall 5 changes. The change in pressure activates the release of the deterrent substance. Like many containers that hold drugs 4, the housing 1 has a lid 70. The lid 70 is attached to the body of the housing 1 by a hinge 7. In some embodiments, the hollows walls 5 and the lid 70 are fluidly connected (e.g., by a tube 81) to form a connected uniform pressure. Thus, even if the user cuts through the lid 70, the pressure drop activates the release of the deterrent substance. Furthermore, in some embodiments there is a reservoir of compressed gas 100 inside the walls 5 to maintain a consistent pressure within the walls over time. In some embodiments, there may be an adjustable pressure valve 90 that controls the pressure within the walls 5. To that end, a pharmacist who is giving out the medication may pressurize the container at the time of delivery to the patient and/or activate the deterrent system.
In some embodiments, the wall 5 and/or the lid 70 contain an electrically conductive matrix 80, such as a matrix of wires 80. If the wires 80 are broken and/or cut, this triggers a solenoid that pushes the tip 114 of the piston away from the container 34, and the deterrent substance is positioned (e.g., sprayed) onto the drug 4. Thus, illustrative embodiments release chemical deterrent when the user cuts and/or breaks through the housing 1.
Illustrative embodiments have a touchscreen 92 on the lid, through which the locking mechanism 32 may be accessed. In some embodiments the bottle is operated using simple buttons. The patient enters their code using the touchscreen 92 (for example, the code may be provided or set up by the medical practitioner). The touchscreen 92 thus may control a locking mechanism 32, act as a locking mechanism 32 by having a biometric scanner, it could have reminders and displays that notify the user (e.g., via sound or pop-up notifications), a calendar, and other normal functionalities associated with touch-screens (e.g., such as in a smart-phone).
The signal from the touchscreen 92 may be sent through wires 94 to a motor 96 that is powered by a battery 98. The motor causes gears 88 to rotate, which in turn rotates a carousel 102. The carousel 102 has spaces 103 cut into it to accommodate a wide variety of medicine 4 shapes and sizes. In this embodiment the carousel has spaces 103 for 16 dosage units. However, the carousel can have more or less spaces 103. Not all the spaces 103 need to be filled by medicine 4. For example, one space 103 may be left empty so that there is not a drug 4 in the chute 107. Medicine 4 may be placed into the carousel 102 by a physician or pharmacist before the lid 70 is closed. In illustrative embodiments, once the lid 70 is closed, it cannot be opened without causing the abuse deterrent substance 34 to deploy, even if the passcode is correctly entered (e.g., because the passcode rotates the carousel 102—it does not open the lid 70). Furthermore, in some embodiments, there may be multiple tiers of the carousel 102 to facilitate holding more drugs. Illustrative embodiments of the carousel 102 may be porous so as not to prevent the deterrent substance from spraying through the tired carousel.
The lid 70 may be sealed closed by a clasp 104. The bottle may be sealed by a ring 106 that also holds the medicine 4 in place if the bottle is inverted. The ring 106 is porous, so as to not prevent the medicine 4 from being coated by the abuse deterrent substance 34. The carousel 102 can rotate and stop, positioning the medicine over the chute 107. The medicine then drops down the chute 107. The medicine may pass a counter 108. In this embodiment the counter 108 is a gate, however the counter can also be an optical counter. In some embodiments there is a gate and an optical counter that is located under the carousel 102. In some embodiments, the to counter 108 only goes one-way, so as to prevent a user from trying to access the drug through the chute 107. In some embodiments, a sensor is connected to the chute 107 and to the valve 90, so that tampering with the chute 107 activates release of the deterrent substance (e.g., by opening the valve 90 and dropping the pressure in the walls 5).
The bottle can be programmed by the physician or pharmacist to only dispense medication 4 at certain intervals. The bottle can also be programmed to provide reminders to take medication 4. The bottle can also be programmed to deploy the abuse deterrent substance after a certain interval, for example after a week, or after a month, of after six months. The timed deployment of the abuse deterrent substance removes the useful opioid from circulation, and thereby prevents an excess of unused opioid that could lead to misuse or abuse.
The device 2 may have a processor (not shown) that may control the valve 90. For example, the processor may be a part of the touchscreen 92. When the valve 90 is opened, the bottle walls 5 lose pressure, the abuse deterrent substance 34 is sprayed onto the drug 4. In some embodiments, the valve may open automatically at a week, month, three-months, six-months, and/or at the expiration of the medicine 4. Manipulation of the chute 107, the counter 108, and/or the carousel 102, may cause the valve 90 to open.
In alternative embodiments, the walls 5 may contain a conductive wire matrix (in addition to, or instead of, pressurized air), a solenoid may cause the abuse deterrent substance to deploy if a wire 80 is cut. In some embodiments, the walls may be pressurized and include an electrical matrix, thus, the bottle may have a pressure sensor 110 to monitor the pressure within the walls. The bottle walls 5 may be formed in part or in whole from a material that is porous, to allow a precisely controlled release of pressure. This precise release of pressure can cause the abuse deterrent substance to deploy after a predetermined period of time even if the electronics fail (e.g., after 1 month, or six months).
In some embodiments, the lock 32 is a biometric scanner such as a fingerprint scanner. Accordingly, the lock 32 does not open unless the fingerprint which has been programmed is pressed against the lock. The lock 32 can also incorporate a timer that is set to the expiration date of the contained medicine, or to a set interval of a treatment period assigned by a health care worker. As an illustrative example the timer could be set to lock the bottle after a 7 day course of pain medicine is complete.
In some embodiments, the device 2 may be coupled to a dosage counter. Depending on the type of drug 4, the dosage counter may be configured to count the dosage in number of pills, milliliters of fluid, and/or milligrams of drug that is released from the housing 1. After a threshold of dosage has been reached, the dosage counter may be configured to activate the locking mechanism. Furthermore, in some embodiments, an actuator may be coupled to the dosage counter and may cause the physical deterrent to move to the secured position.
Additionally, or alternatively, a dosing scheduler may be coupled to the locking mechanism and/or physical deterrent. The dosing scheduler may control the locking mechanism to unlock only during certain times of the day (e.g., for 30 minutes, between 9 AM and 10 AM, once every other day, etc.).
The device 2 may be network enabled (e.g., Wi-Fi), to receive updates from medical staff (e.g., prescribing doctor) regarding the amount and timing of drug to be released. Additionally, the device may forward data to the doctor regarding the timing and dosage of drug accessed. In some embodiments, the device 2 has network connectivity capabilities and can communicate with an external site and provide information or receive information. In some other embodiments, the device 2 may have an electronic display which may be a touchscreen. The device 2 may also incorporate audible, visual, vibratory or other types of alerts and reminders for the patient 8.
The housing 1 may be any container, e.g., a pharmaceutical bottle formed from pharmaceutically acceptable material. The pharmaceutical bottle 1 can be formed from HDPE (high-density polyethylene), polypropylene, polyethylene terephthalate, high density polyethylene, polyvinyl chloride, polystyrene, polylactide, stainless steel, aluminum, and/or glass, and/or may be clear, tinted, or opaque. As described previously, the bottle may hold the drug 4 therein.
In some embodiments, the walls 5 of the housing 1 may be hollow and filled with pressurized air. In alternative embodiments, the walls may be filled with compressed nitrogen. Compressed nitrogen does not have water vapor in it and may keep the pressure within the walls 5 more steady than pressurized air. It should be understood that a variety of different compressed gases may be used, and that discussion of “air” is merely intended to facilitate discussion of illustrative embodiments, and not to limit them thereby.
In some embodiments, a pressure cylinder 127 is attached to a piston 109. In the embodiment shown, the piston 109 is a pressure piston 109 which is attached to a sealing needle 121 and sealing needle cover 122. The sealing needle 121 presses through the sealing needle cover 122, into the abuse deterrent container 24 and seals it. A locking piece 124 and an o-ring 123 are attached to the pressure cylinder 127. As shown in
If the drug 4 is improperly accessed (e.g., by cutting through the walls 5), the pressure inside the wall 5 changes. The change in pressure activates the release of the deterrent substance. Like many containers that hold drugs 4, the housing 1 has a lid 70 and a sealing cup 125. In some embodiments, the hollows walls 5 and the lid 70 are fluidly connected (e.g., by a tube 81, as shown in
Illustrative embodiments have a button 116 covered by a button cover 117 near the base of the housing 1. In other embodiments the button 116 may be many buttons, a touch screen, a biomentric sensor, or a wireless receiver. The term button is simply an illustrative term and not intended to limit the ways a user may attempt unlock or access the medication 4.
In some embodiments, a motor 96 is attached to a battery 98. The motor 96, which may be a stepper DC motor, causes gears to rotate, which in turn rotates the carousel 102. The carousel 102 is supported by a carousel support 118 underneath and a carousel support on top 119. In some embodiments the carousel has spaces 103 for multiple dosage units (as shown in
In some embodiments there is no motor 96 (not shown). In these embodiments pressing the button 116 may allow for the manual rotation of the carousel within the bottle. In some embodiments, pressing the button 116 unlocks the carousel 102 for about one second, or about five seconds, or about ten seconds, or about twenty seconds, or about thirty seconds, or about forty-five seconds, or about one minute, or about two minutes, or about three minutes, or about four minutes, or about five minutes, or for an unlimited period of time. In some embodiments the bottle may rotate in half, or it may have a gear that is exposed and can be manually rotated. In some embodiments pressing the button does not automatically rotate the carousel, but rather unlocks the carousel to allow for manual rotation.
Although the above discussion discloses various exemplary embodiments of the invention, it should be apparent that those skilled in the art can make various modifications that will achieve some of the advantages of the invention without departing from the true scope of the invention.
